` To all 'whom t may concern v 'f Be it known that I, CLirFonn WILLS, a

'citizen of the United States, residing at Salt Lick, in the county `of Bath and State of Kentucky, have invented certain new and" useful Improvements in' Railway Switches,

. of which the following is a specification.

A still further object of .myinvention is to. provide avrailway switch,y which is vpositive in its action. y v y A stillfurther object of my invention is to provide Aa railway switch, .in which the operating mechanism will not interefere lwith the ordinary control mechanism of a vehicle.

A still yfurther object of my invention is to provide a vrailwayl switch and an operatin mechanism therefor, that is strong, du-V ra le, simple and inexpensive in its con struction, whereby the number of working parts are reduced to a minimum, and which -is well adapted t `they use for whichit is designed.

mechanism mounted thereon,

` parts throughout the same. v

vOther objectsand advantages of the inventionwillbe apparent during the coursey of the following description. f

" In the accompanying drawings `formingr a partof the specification and in which like numerals are employed to designate like Figure 14 .is 4a top plan view of a railwayI switch, showing a part of the operating "Figure 2is a side elevation of a railway s ktherefor, n d. l

-In the drawings, wherein for the 'purpose of illustration is shown a preferred embodiment ofmy invention, the numerallO represents any well known forni of a vehicle such as `a Streetcar ora railway train, which runs on a 'track '11.'. The track`11v is provided with a switch 12, .thetrackupo'n which the vehicle vis yto run being Uoverned f bythe point 13, that isifxthepoint is in the position as is clearly illustrated in Figure 1, the. train will remain on the main track, but yif the `point isf moved they train vwouldfollow around the switch 12.

p Mounted" in any convenient place, within .easy reach ofthe operator `of the vehicle is a `standard'llprovided with notches 15.A A

. vertical shaft 16is so mountedupon the front platform of theV vehicle, -soA as to exltenda substantial distance-.above the. same'V and which is provided atonefend withy an operating lever 17shaving aA handle-18, said operating lever 17 adapted tolengagev the notches 15 of the standardlt. r'The'standard 14 is preferably` provided with three notches 15, onefof which wewmay term yane'utral one and the other two ywe m'ay term the right and left'notches, said operating lever 17 is adapted to be swungeithe'r to the lright orleft so aslto engage anv one of the thre notchesland held `in said position. 'I

The lower end ofthe'verticalshaft 16 is provided with a semi-circular plate 19 having a ydownwardly'extending pin 20 mount..

asy

ed near the outer extremity thereof. said .plate 19 being` adaptedrto swing with the shaftl."

The `numeral 21mdesignatesI a wheel or roller which is mounted on a verticallyextending shaft or link22 which is adapted tofslidewithin a guide sleeve. or lipf23 which is mounted upon thef'ramelof the vehicle. The numeral 24 represents,l a bell crank which is nivotedzupon the framey ofthe car Y by meanskof a loolt257 and one arm of which is connectedtotheupper extremity of the. y

vlink 22 :byineans of a'bolt 26, and the other arm of the bell'crank'24c bcingiconnected to the link -27 lby' meansffof a' bolt .The

other end of' the link 27 kis connected to ythe bell crank 29y bymeansor" a bolt 30, said bell crank being pivoted at point 31, and

the other arm of which is connected to a cam4 32 by means of a pin '33, said cam plate being provided with slot 34 which is adapted to receive the pin 20. As the opyerating'mechanism on the right and left side of the vehicley are identical it is only neces- .sary :to describev one, as will readily beunderstood byy an inspection of the drawings.

It will thus be seen that by moving the operating lever 17 the shaft 16 will be moved kthereby swingingthe semi-circular plate 19 which carries the pin 20, whichy in turn will move 'the cam '82therebyrocking fthe bell crank 29 which ywill move the link 27, which in 'turn will rock the "bell crank 24 which vwill move theflink 22 upwardly ory downk'wardlyfdepending lfupon the directionl in which'theperating lever 17 is moved.

vReferring,now-to the trackmechanism, the numeral 3 5 designates the cam upon which "the roller :21' comes in contact. The :cam 35 kis .in the shape oit anbell crank, which is ment of the cam 35 therein A lockingmemyber for the 'cam 42 is pivoted to the rail fgat 48 and,` has at one end any 'form vof lock x44, andisprovided at-the opposite.v end with angoutw'vardly extending ange, which is adapted-.to 'engage aboss 46 on the Vlink 38.

It `will' thus kbe seen, that the outwardly eX- ftending ,iiangexforined .on the pivoted lockingmember 42,v will engage the boss 46 r`formed on the link 38,and the locking member 44 formed on the opposite end of the locking 'member 42, ywill engage fthe inember `35 so ask to hold the point in the desired position, until the opposite cam has been struck or operated by the cam operating me`chanism,whereby the locking member will be `released and the opposite locking-meml bergthat the locking member associated Ywith the opposite-cam :Will bevthrown into an operative position. The other-end of the link'SS is connected toa bell crank 47 vwhich k.is'pivoted at 48 "and the other 'arm of kthe bell 'crankrbeingfcoiiiicted '49 to ja link 50, which ycarries "a pin `51 whi'h'is vconnected to. the pointsl. "said pin 51 beingadapted -Havingset fotlrthe construction and arin Figure l. As is yshown in Figure 1 of l the drawings, the point 13 is in'such a position, that if left unniolested the street car will continue on the main track. Assume now,that the 'inotorman desires to leave the vmain track 11 and go onto the switch 12. By looking at Figure 6, we find that the right hand lwheel `21 is lowered so that it will strike the right hand cam 35, thereby leaving the point 13 in the positionhas4 is shown in rFigure 1. Now ifthe motorman desires as above stated, to switch to'lthe switch 12 he wouldpull the lever "17 into the position as is shown in dotted lines in F igure 6, thereby raising the right hand wheel 21 rand lowering the wheel 21on the left hand side. The left hand wheel 21 will now strike the'cam 35 on the left handV side of the track, and through the movement ot switched onto the switch 12 asis ishown in Figure 1. lf the 'succeeding -motorman, that is the motorman of thejcar behindthevone that has gone on the switch desires vto move the pointin such a manner that her will c ontinue on the main track 11, he merelyshifts the lever 17 into the position as is shownin dotted lines lin Figure 6, and the point 13 will be moved direct into the position as is shown in Figure 1 oit thek drawings.

Vile Iwill' now go thioughvthe detail jmovement of the various parts when the/switch point 13 is moved.y The motorinan irst shifts the lever 17finthedesired position, thereby swinging the shaft -1'6 which rocks the semilcirc'ular plate 19 whichmoves the pin 2O in vthe vslot 32, which in gturn rocks the cam 32 which is pivotedr V to the bell crank 29 at'33, saidbell crankmoving the link 37, which rocks the bell crank24which raises orwlowers thelink 22 which ycarries the wheel 21,'according to which-positionthe lever 17 is arranged. If the wheel 21 is depressed 'so as to strike the cam or bell crank V35, the link 38 kwill accordinglybe moved through the medium of the bell crank 47, the link 50 will likewise be moved, landthe pointf1-3 will be moved in whichever direction. the lever`=17 has been setyfo'r..A It will of course be understood that if'th'e point 13 is in the desired position "and ythe motorman is not requiredv to set the sanie,fthe lever '17 will be left in a neutral position. It will readily -be seen that this same track IHSChanisni could be utilizedto operate 'av'signah lwithjust as much satisfaction as in moving rthe point 13,r that is va similar mechanism as is disclosed inl the drawings,v could v*be so arranged that a train or 'street car vapproaching a lroad-crossing would "automatically start an `audible or visual signalin opera tion to warn the approach of the vehicle, although the 'primarr object is the Yoir''e disclosed in the drawings.

It is to be understood .that the torni of downwardly extending pin, a bell crank con# my invention as above shown and described is to taken as a preferred embodiment of the same, and that various changes in the form, size and arrangement of parts may be resorted to, without departing from the scope of my invention as hereinafter claimed.

Having thus described my invention what I claim as new is l. In combinationwith a Vrailway switch including a crank, a link connected tof said crank, a bell crank pivoted to said switch, one arm of which is connected to said link, a second link running substantially parallel to said track and connectedat one end to the other arm of said bell crank, a cam bell crank pivoted to said track, one arm being connected to the other end of the second named link, and means adapted to strike said cam bell crank to operate the point.

2. In combination with a railway switch including a point, point throwing mechanism associated with said switch, including a cam, means mounted on a train tocontact with said cam, comprising an operating shaft provided with an operating lever, a semi-circular plate secured to the lower end of said shaft, and being provided with a downwardly extending pin, a cam plate having a slot adapted to receive said nected to the end of said camplate, a link y connected to the other end ofsaid'camcplate,

a second bell crank connected with one arm to said link, and aroller adapted to contact with said point drawing cam, mounted on the other varm of said bell crank. V y. 3. The combination with a point throwing mechanism including a'cam, means to lock said cam, and means mounted on a train adapted to contact 'with said cam.

l. The combination with a point throwing mechanism including a cam, a pivoted locking member associated with said cam,-and

mea-ns mounted on a train yadapted to'conv 45 tact with the cam.
